Trying to parse twitter trends - iphone

Question

Im trying to parse twitter trends but i keep getting a parser error at "as_of". anyone know why this is happening?
EDIT:
Here is the code im using
NSMutableArray *tweets;
tweets = [[NSMutableArray alloc] init];
NSURL *url = [NSURL URLWithString:#"http://search.twitter.com/trends/current.json"];
trendsArray = [[NSMutableArray alloc] initWithArray:[CCJSONParser objectFromJSON:[NSString stringWithContentsOfURL:url encoding:4 error:nil]]];
NSMutableDictionary *dict = [[NSMutableDictionary alloc] init];
for (int i = 0; i < [trendsArray count]; i++) {
dict = [[NSMutableDictionary alloc] init];
//[post setObject: [[currentArray objectAtIndex:i] objectForKey:#"query"]];
[dict setObject:[trendsArray objectAtIndex:i] forKey:#"trends"];
//[dict setObject:[trendsArray objectAtIndex:i] forKey:#"query"];
//[post setObject:[trendsArray objectAtIndex:i] forKey:#"as_of"];
[tweets addObject:dict];
//post = nil;
}

I'm not exactly sure what your problem could be but I've had a play with the twitter api and CCJSON and have got some sample code that seems to work. If you cut and paste it into the applicationDidFinishLaunching method of a new project and include the CCJSON files it will just work (hopefully).
This code will take the trends json from twitter, output the as_of value and create an array of trends.
// Make an array to hold our trends
NSMutableArray *trends = [[NSMutableArray alloc] initWithCapacity:10];
// Get the response from the server and parse the json
NSURL *url = [NSURL URLWithString:#"http://search.twitter.com/trends/current.json"];
NSString *responseString = [NSString stringWithContentsOfURL:url encoding:4 error:nil];
NSDictionary *trendsObject = (NSDictionary *)[CCJSONParser objectFromJSON:responseString];
// Output the as_of value
NSLog(#"%#", [trendsObject objectForKey:#"as_of"]);
// We also have a list of trends (by date it seems, looking at the json)
NSDictionary *trendsList = [trendsObject objectForKey:#"trends"];
// For each date in this list
for (id key in trendsList) {
// Get the trends on this date
NSDictionary *trendsForDate = [trendsList objectForKey:key];
// For each trend in this date, add it to the trends array
for (NSDictionary *trendObject in trendsForDate) {
NSString *name = [trendObject objectForKey:#"name"];
NSString *query = [trendObject objectForKey:#"query"];
[trends addObject:[NSArray arrayWithObjects:name, query, nil]];
}
}
// At the point, we have an array called 'trends' which contains all the trends and their queries.
// Lets see it . . .
for (NSArray *array in trends)
NSLog(#"name: '%#' query: '%#'", [array objectAtIndex:0], [array objectAtIndex:1]);
Hope this is useful, comment if you have any questions,

PS I used this site to visualise the JSON response - it made it much easier to see what is going on - I just cut and paste the JSON from twitter into it :)
